if the low oil pressure light is on and I can't start my car what should I do?

they won'y go off until the engine is running! never noticed all those lights coming on every time you turn the key on,and all of them go off except those 2 until you start the engine(it's a bulb check) check the oil pressure unless the engine is already locked up.

Find a qualified repair shop, have your car towed in and have it diagnosed.
